If a redirect occurs during an HTTP response, the browser follows it automatically
and you won't see the toolbar or the profiler of the original URL, only the
redirected URL.

When setting this option to true, the browser stops before making any
redirection and shows you the URL which is going to redirect to, its toolbar,
and its profiler. Once you've inspected the toolbar/profiler data, you can click
on the given link to perform the redirect.

When the toolbar logs Ajax requests, it matches their URLs against this regular
expression. If the URL matches, the request is not displayed in the toolbar. This
is useful when the application makes lots of Ajax requests or they are heavy and
you want to exclude some of them.
